Adductor hallucis muscle (anatomy)

Authoring team

Adductor hallucis is one of the third layer of intrinsic foot muscles.

It originates from two heads:

  • oblique head from the bases of the second to fourth metatarsals
  • transverse head from plantar ligaments and deep transverse ligaments around the third to fifth metatarsophalangeal joints

It inserts into the:

  • lateral side of the base of the proximal phalanx of the hallux
  • lateral sesamoid bone of hallux

Its main action is to adduct the big toe. Also, it supports the transverse arch.

Adductor hallucis is innervated by the deep branch of the lateral plantar nerve (S2, S3).
